MRRTrackChatGPT sells subscriptions to individuals and organizations. OpenAI also bills API usage separately and offers advertising on some plans. These revenue streams do not all belong to the ChatGPT product alone.
Individual subscriptions
Regular users
Paid plans provide capabilities and limits above the free offering.
Official source ↗Organizational plans
Businesses and institutions
Organizations buy team access and management capabilities for their needs.
Official source ↗Usage-based API
Developers and software companies
Products integrating OpenAI models use API billing that is separate from ChatGPT subscriptions.
Official source ↗Advertising
Advertisers
Some plans may include ads. Availability depends on the plan and rollout.
Official source ↗What these figures do not tell you
A funding round finances the company; it is not revenue. Total OpenAI revenue, ChatGPT subscriptions and API usage have different scopes. No revenue split is estimated here.
What you can learn from it
For a small SaaS, the useful lesson is the billing unit: access, seats or consumption. If each action uses a paid API, test margins on your heaviest users before promising unlimited usage.
